just read the comments to this and am intrigued. there are certain points with which i agree very much, but i at heart i disagree. for myself at any rate. (i don't think i know enough about fandoms as a whole to comment broadly.)

edit to add more clarity:
(which is tricky cos i can't view the comments while i edit this :P )

agree with: not being restricted by the 'girl' archetype. sometimes it's about producing a new 'level' power structure, so far as the personalities themselves making one rather than battling against the gender constructed assumptions.

disagree with: it 'not being about homosexuality at all'. i read femmeslash because i want to read about women. i read slash when i want to read about men. sometimes i read the stories purely because of the people/characters themselves. sometimes i love the dicks. sometimes i love seeing men having broader roles than society gives them.

i love reading poly fic for a whole group of reasons, too.
